type of differential that compensates for speed differences

• axle
• wheel

A differential bearing ring seal is a component that seals the differential bearing.

• transmission

Rubber components that mount the gearbox and differential to the frame

• gearbox
• differential
• mounting

A device that locks the differential to provide maximum traction

• drivetrain
• component

Mechanically self-locking center differential for four-wheel drive

• four-wheel
• drive

a component that compensates for different wheel speeds in 4WD systems

• 4wd
• differential

A system that directs power to the wheel with better grip, reducing tire wear

• differential
• traction

compensates for difference in wheel speeds on driven axle

• axle
• wheel

Shaft that drives the differential in a vehicle

• differential
• syncro
• gearbox

An extension of the electronic differential lock function, responding to loss of traction

• differential
• traction

prevents wheels from spinning freely, directing power to wheel with better grip

• axle
• wheel
• traction

A device within a differential that couples both wheels for additional traction

• vw
• drivetrain
• traction

Shaft that transmits power from the engine to the gearbox

• differential
• syncro
• gearbox

A device that controls the flow of vacuum to the differential lock

• drivetrain
• component

A device in the front differential of a Syncro that provides the switching action between the rear diff/wheels and the front.

• syncro
• viscus

In a Syncro drivetrain, a driveshaft decoupler disconnects the prop shaft so the front axle is no longer driven through it; it is not the front differential lock. A Gerry discussion on 16 May 2004 compares the original non-viscous-coupling layout, which used a driveshaft decoupler, with viscous-coupling Syncros while debating front-lock behavior. The thread is historical community discussion, not a retrofit procedure; identify the drivetrain configuration before interpreting parts or controls.
